2.4 Å and 6 Å. Wavelengths can easily be changed under computer control, since they are all obtained by a simple rotation within the Ge[hhl] plane. A large graphite filter can be switched in to provide ... provide a very clean beam at 2.4 Å, and a cold Be-filter can be used for longer wavelengths.

detector can be changed between 10’ and ˝open˝. The sample table can support the mounting of high-field cryomagnets (up to 12T and 15T, respectively in the polarised and unpolarised modes). IN22 can be operated ... or polarised mode. Vertical guide fields are permanently installed. The incident/final polarisation can be continuously selected in the ...

i = 2.66 Å -1 and 4.1 Å -1 are 0.82(3) meV and 3.05 (15) meV, respectively. Polarisation analysis can be performed in combination with the standard ILL 2.5 T and 6 T vertical-field and 4 T horizontal-field ...

associated with each Cr 3+ ion is only 2.48 μB rather than the predicted 2.97 μB. The loss of moment can be attributed to covalent mixing of the Cr 3d electrons with O 2p orbitals in π-type antibonding orbitals

First test of an 3He neutron spin filter The nuclei of a helium-3 gas (3He) can be polarised. Thanks to the strong spin-dependancy of the neutron absorption a bottle filled up with that polarised gas would
